FREIGHT 57 conferences referred to in an earlier chapter. These rates of freight are adjusted from time to time. The master has a lien on all goods for freight due, but not paid, and until these charges are paid he may retain cargo. The consignee is not entitled to receive the goods until the freight has been paid, and the shipowner is strictly not entitled to his freight until he has delivered the cargo, unless contract calls for freight in advance. If the master delivers the cargo before payment of freight he may lose his lien, therefore he is entitled to claim his freight when he is ready to deliver. Charter-party freight is fixed at an agreed rate for so much per ton (1,015 or 1,016 kilos) or other trade measure. Here there is no stipulation for weight or measurement cargo. Charter-party freight is nearly always due on delivery of the cargo, and when the contract is silent as to the time for payment it is understood that freight is paid concur- rently with delivery. The term ** Freight paid ton by ton delivered/* must not be taken to mean what it literally says. Here a total of the day's work and cargo discharged is notified to the charterer who pays freight on that quantity. Again, a carrier is not entitled to his freight until cargo is delivered, and in the event of the ship not reaching its port of discharge no freight may be claimed. The shipowner is not entitled to doim projrata freight for the part of the voyage he has carried the goods, but if the ship does not complete the voyage, the master may make arrangements to tranship the cargo to final port of discharge and thus earn his freight, all charges for such transhipment or forwarding being for his account. There is an exception to this rule, however; if the con- signee is notified that the ship has stopped short of its destination, and voluntarily agrees with the shipowner to take delivery at the intermediate port, then pro rota freight would become chargeable. Whenever disputes occur regarding the weight of cargo carried, the person who requires the goods to be checked, must pay costs of such check-weighing.
